NOTE: the Sandbox page is important, use that over any regular wiki page when possible (See link to Sandbox below). Also, for those who have created an account, one's User Talk page is also useful for testing. For example, my user talk page is here: https://www.mediawiki.org/wiki/User_talk:Cmcmahon

Setup

Create a global account on any wiki and login. This is not required, but it makes several things easier:

Any edits to pages preserves the identity of the editor. This is of particular interest for the Sandbox page

Provides a User_talk page, which is a good place to do testing

Allows persistent setting of various user preferences relevant to testing
